Flowalyzer

Flowalyzer is a tool you might want in your toolkit if you're dealing with network security. It's super important to keep networks safe in business settings so that no sensitive data leaks out and no harmful stuff sneaks in. Plus, maintenance is key, and there are tons of tools out there to help with that. Flowalyzer is one of the best for testing and tweaking your network connections.

Simple Interface with Powerful Tools

At first glance, the app looks pretty straightforward and clean. But don't let that fool you! It's really made for someone who knows their way around networking. The layout has different tabs, each one representing a specific tool that works as a listener, generator, configurator, or communicator.

Monitoring Network Ports

The listener tab is super helpful for keeping an eye on certain ports. It updates the results in real-time and shows info like the exporter IP, host name, port type, and count. You can check out NetFlow and sFlow data packets to see which host is sending the most traffic.

Generating Flow Data Packets

If you want to create flow data packets to send and receive, this feature gives you a clear picture of how many flows and packets per second are moving through your network. You can even make a list filled with custom flows! These flows can be fully tailored to fit your needs—just fill out fields like protocol, source IP, destination IP, port number, or NetMask! Plus, it supports both versions 5 and 9 NetFlow for collector details.

Configuring Cisco Routers

If you head over to the “Configurator” tab, that's where things get exciting! Here’s where you set up several Cisco routers so they can export those NetFlow data packets. All you need to do is enter the host name or IP address along with some custom credentials.

A Handy Utility for Network Monitoring

All in all, Flowalyzer is a useful tool for checking packets on your network. It's packed with tools for monitoring hardware and software setups so that sFlow and NetFlow are possible. With just a little knowledge under your belt, you'll have no trouble getting everything set up!
